You open one file or several, or snap them. They are read into memory on this device and nowhere else.

Blotmarked reads the whole document and proposes what to remove under the privacy rules of your jurisdiction. One decision per value covers every page it appears on, and you can override any of it.

Detection is never the last word. A page sweep walks you through the document so handwriting, stamps and text inside images do not slip past. Then the copy is saved beside your original.

Close the app and the working copy is gone. Nothing is written to storage. Both files are yours, and Blotmarked can prove what it removed without holding anything of yours.
